Assembly And BIOS
The XPC model SX58H7 is said to be both CrossFire- and SLI-compatible, but Shuttle included only the CrossFire bridge in our sample. Two SATA cables are pre-mounted in the case, while the third is supplied in the accessory kit.
Included but not shown are a screw pack and driver CD.
Shuttle’s SX58H7 has enough room even for our super-tall Kingston ULT1 memory modules under its drive tray.
Zotac’s GeForce GTX 260² 896 MB has become our most recent benchmarking standard card, and it fits quite nicely.
There’s even enough room for a GeForce GTX 295 or, if you prefer, a Radeon HD 4870 X2.
BIOS
Shuttle provides an extremely simple “Frequency/Voltage Functions” menu that still contains all the settings most overclockers require. Our only limitation was in memory speed selection, which is a problem Shuttle promises to address quickly.
| BIOS Frequency and Voltage settings (for overclocking) | |
|---|---|
| CPU Reference Clock | 100 to 250 MHz (1 MHz) |
| CPU Multiplier | Yes |
| DRAM Ratios | DDR3-800, DDR3-1066 |
| PCIe Clock | 100 to 150 MHz (1 MHz) |
| CPU Vcore | 0.850 to 1.80 Volts (0.025 V) |
| CPU VTT (Uncore) Volts | 1.125 to 1.80 Volts (0.025 V) |
| IOH (Northbridge) Core | 1.125 to 2.00 volts (0.025 V) |
| ICH (Southbridge) Core | 1.125 to 2.00 volts (0.025 V) |
| DRAM Voltage | 1.525 to 1.900 Volts (0.025 V) |
| CASLatencyRange | tCAS:5-10; tRCD: 5-10; tRP: 5-10; tRAS: 14-28 |
All of these function fit into a single menu that requires only a two-page scroll to view in its entirety.
The XPC SX58H7 also has a “User Habit Auto Set” sub-menu capable of storing two custom-BIOS configurations.
